In Lua 5.2 'require' no longer puts the value returned by the module into the global namespace, so you should do something like: 

	cb = require("cb") -- on the lua interpreter command line

	local cb = require("cb") -- in source code
If you depend on the old behavior you have to set the value of the global variable 'cb' yourself, using something like 

	lua_pushvalue(L, -1);
	lua_setglobal(L, "cb");

(right after luaL_newlib)

In my own code I just use

	local mymod = require 'mymod'

This has better performance because 'mymod' is a local variable.

I have a single-function module build with Visual Studio 2010 that
apparently loads but its function cannot be accessed because the entries
in package.loaded are nil.  Below print(type(cb)) returns nil while all
other k's in package.loaded return table.

Obviously, I am doing something wrong?

Here is a link to the code for the module:
